Introduction 1 Introduction Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world of unique, creative, and affordable solutions to the vast range of problems that confront the video, audio, presentation, and broadcasting professional on a daily basis. In recent years, we have redesigned and upgraded most of our line, making the best even better! Our 1,000-plus different models now appear in 11 groups 1 that are clearly defined by function.
Getting Started 2.1 Quick Start This quick start chart summarizes the basic setup and operation steps.
Overview 3 Overview The TP-185 is a high performance, 8 channel VGA/UXGA1, audio and RS-232 to CAT 5 transmitter for high resolution video, stereo unbalanced audio and RS-232 signals. The CAT 5 outputs can be connected to any Kramer compatible TP receiver, for example, the TP-126. The TP-185 can also route data from the RS-232 or RS-485 port to any of the CAT 5 outputs.
Defining the TP-185 8 Channel UXGA/Audio/RS-232 to CAT 5 Transmitter 4 Defining the TP-185 8 Channel UXGA/Audio/RS-232 to CAT 5 Transmitter Figure 1 and Table 1 define the front and rear panels of the TP-185, 8 Channel UXGA/Audio/RS-232 to CAT 5 Transmitter.

Installing the TP-185 in a Rack 5 Installing the TP-185 in a Rack This section describes what to do before installing in a rack and how to rack mount the TP-185.
Connecting and Configuring the TP-185 6 Connecting and Configuring the TP-185 This section comprises connecting: • The TP-185 (see Section 6.1) • To the TP-185 via RS-232 (see Section 6.2) • To the TP-185 via RS-485 (see Section 6.3) • Multiple TP-185 units via RS-485 (see Section 6.4) 6.
Connecting and Configuring the TP-185 1. Connect up to eight VGA/WUXGA computer graphics sources (for example, multimedia computers) to the Video INPUT 15-pin HD connectors. 2. Connect up to eight unbalanced stereo audio sources (for example, the audio source of the computer or a DAT player) to the eight AUDIO INPUT 3.5mm mini jacks. 3. Connect the eight OUT STP/UTP connectors to up to eight TP receivers. 4. If required, you can connect a PC and/or controller to the: RS-232 terminal block (see Section 6.
Connecting and Configuring the TP-185 6.4 Connecting Multiple TP-185 Units via the RS-485 Bus You can connect up to 8 TP-185 units via the RS-485 bus with control from a PC or serial controller. To connect up to 8 TP-185 units via RS-485 (see Figure 3): 1. Connect the RS-485 terminal block of the first TP-185 to the RS-485 terminal block of the second TP-185, and so on (see Section 6.3), connecting all the TP-185 units via the RS-485 terminal blocks. 2.
Setting the DIP-switches on the TP-185 7 Setting the DIP-switches on the TP-185 The DIP-switches on the TP-185 perform the following functions: • RS-485 termination • Reply enable/disable • Reply machine number • Baud rate • Hardware/software mode Moving a DIP-switch down turns the switch on, moving it up turns the switch off. Note: Changing any DIP-switch requires that you cycle power on the TP-185 7.1.1 Setting the RS-485 Bus Termination The DIP-switch sets the RS-485 bus termination.
Setting the DIP-switches on the TP-185 When DIP-switch 1 is: • Up, Reply is disabled (default) • Down (ON), Reply is enabled 7.1.3 Setting the Reply Source or Machine Number DIP-switches 2, 3 and 4 set either the reply source (in Hardware mode Table 2) or machine number (in Software mode Table 3).
Setting the DIP-switches on the TP-185 7.1.4 Setting the RS-232/RS-485 Baud Rate DIP-switches DIP-switches 5, 6 and 7 set the serial port baud rate in both Hardware and Software modes according to Table 4. Note: In a multiple device configuration, all devices must be set to the same baud rate. Figure 7: TP-185 Baud Rate DIP-switches Table 4: Serial Port Baud Rate DIP-switch Setting Baud Rate 1200 2400 4800 9600 (default) 7.1.
Wiring the Twisted Pair RJ-45 Connectors 7.1.5.2 Software Mode In Software mode, the TP-185 routes the data and reply based on the Protocol 2000 commands received from the PC or other device connected to any of the inputs. The following example illustrates a typical command sequence. The destination and return paths to and from the end-user device are set (TP-185 control commands), then an end-user device command is sent to the defined destination.
Technical Specifications 9 Technical Specifications Technical specifications of the TP-185 are shown in Table 6. Table 6: Technical Specifications 1 of the TP-185 INPUTS: 8 UXGA on 15-pin HD connectors (VGA through WUXGA) 8 unbalanced stereo audio 3.5mm mini jacks OUTPUTS: 8 TP on RJ-45 connectors RESOLUTION: Up to WUXGA (1920 x 1200) RANGE: Up to 100m (328ft) MAX. OUTPUT LEVEL: VIDEO: 1.6Vpp AUDIO: 2.
Default Communication Parameters 10.1 Kramer Communication Protocol 2000 The RS-232/RS-485 Protocol 2000 uses four bytes of information as shown in Table 8. The data rate is set by the DIP-switches (see Table 4), with no parity, 8 data bits and 1 stop bit.
Default Communication Parameters Table 9: Instruction Codes for the TP-185 INSTRUCTION # DESCRIPTION DEFINITION FOR SPECIFIC INSTRUCTION INPUT NOTE OUTPUT 2C CONTROLS THE STATUS OF A PORT 0–close 1–open Output bit: O0–O5 = output # or 0 for all outputs O6–0 = Tx; 1 = Rx 1, 2, 4, 5 2D READS THE STATUS OF A PORT 0–open Output bit: O0–O5 = output # O6–0 = Tx; 1 = Rx 2, 3, 4, 5 Note: All values in the table are hexadecimal, unless otherwise stated.
